Ewbob KZ Castor Improved Bass Earbuds with Microphone (Tuning)

KZ Castor breaks through traditional acoustic tuning methods by innovatively adopting a dual-dynamic driver acoustic design. This approach has resulted in the perfect Harman curve that outperforms flagship products from other brands.
KZ Castor features a unique design with two stacked dynamic drivers. One driver is dedicated to producing frequencies around 20-200Hz for bass output, while the other diver handles mid and high frequencies.
Through precise electronic crossover technology, these two divers work synergistically without interference between their frequencies. This enables KZ Castor to deliver powerful and energetic bass as well as stunning mid and high frequencies.
KZ Castor boasts a drop of over 10dB in the 40Hz-300Hz range. Using the acoustic theory that 6dB represents a doubling, KZ Castor's performance in the low-frequency range has decisively outperformed traditional headphones in data.
